When managing your products on Shein, the correct use of Sale Attributes is essential. They help improve product visibility and enhance the user experience on the platform. This guide explains how to fill in these attributes properly in Shoppingfeed and what they imply on Shein’s side.
Key Concepts Regarding Shein Attributes
What is a Sale Attribute?
A Sale Attribute is a variation attribute visible to the customer, such as size, color, or any other product characteristic that allows multiple versions of the same item.
Don’t confuse this with a “classic” attribute like brand or country of origin, which does not create a variation of the product.
What is an SKC?
The SKC (Standard Key Code) is a Shein-specific identifier that groups all SKUs of a product under one main product reference. It is often based on the primary attribute, such as color.
Basic Rules to Follow
Number of Sale Attributes
Each product can have up to two sale attributes:
saleAttribute1 (required in most cases)
saleAttribute2 (optional, depending on the product category)
Setup in Shoppingfeed
These attributes can be filled in automatically or manually on the Autotag page in Shoppingfeed.
Focus on Size Charts (product Measurements)
Some categories require a size chart, based on the intersection of a Sale Attribute (typically size) with physical product attributes like shoulder width, chest circumference, etc (see as example in shein).
In Shoppingfeed, these appear as crossed attributes on the Autotag page, such as:
saleAttribute1 x Shoulder Width
saleAttribute1 x Chest Circumference
Practical Examples
A. Product without sale attributes
Example: a blue handbag with no variations
| Attribute | Value |
| Color | Blue |
| saleAttribute1 | (empty) |
| saleAttribute2 | (empty) |
B. Product with one sale attribute (size)
Example: a garment available only in different sizes
| Attribute | Value |
| Color | Blue |
| Size | L |
| saleAttribute1 | Size |
| saleAttribute2 | (empty) |
C. Product with one sale attribute (size) + size chart
Example: a garment with variations by size + measurement details
| Attribute | Variation 1 | Variation 2 |
| Color | Blue | Blue |
| Size | 50 (L) | 52 (XL) |
| saleAttribute1 | Size | Size |
| saleAttribute1 x Shoulder Width (cm) | 48.8 | 50.6 |
| saleAttribute1 x Chest Circumference (cm) | 117 | 122 |
| saleAttribute1 x Sleeve Length (cm) | 78 | 80 |
Note: Size charts can also include data for both sale attributes combined, if relevant. Use tags like:
saleAttribute1 x
saleAttribute2 x
etc.
D. Product with two sale attributes
Example: a lamp with variations by size and plug type (voltage)
| Attribute | Variation 1 | Variation 2 |
| Color | Blue | Blue |
| Size | Small | Medium |
| Plug Type | 120V | 220V |
| saleAttribute1 | Size | Size |
| saleAttribute2 | Plug Type | Plug Type |
Key Takeaways
Respect the structure required by Shein: no more than 2 sale attributes per product.
Always check if a size chart is required for your product category.
Only fill in size chart data that actually exists in your catalog.
All sale attributes and size chart info must be configured in the Autotag section of Shoppingfeed.
